WATER-HEATER.

Specification of Letters Patent.

Patented April 30, 1907.

Application filed June 22,1906. Serial No. 822,842.

To ail/Z w/tom it may concern:

Be it known that 1, AUGUST GoLDFmN, a citizen of the United States, aresident of Cleveland, county of Cuyahoga, and State of Ohio, haveinvented a new and useful Improvement in l/Vater-Heaters, of which thefollowing is a specification, the principle of the invention beingherein explained and the best mode in which I have contemplated applyingthat principle, so as to distinguish it from other inventions. I

My invention relates to improvements in water-heating devices, andparticularly the class of such devices now quite generally advertised asinstantaneous water-heaters, which are used about the house for quicklyheating relatively small quantities of water, as for toilet and laundrypurposes.

In this class of heaters the fuel employed is preferably gas and becauseof its expensive ness in most localities it is highly desirable that itsheating capacity, or fuel utilized to the fullest extent.

The object of my present invention, then, is to provide a heater thatwill be economical in its operation; as also one that will at the sametime be of simple construction.

To the accomplishment of these ends, said invention consists of meanshereinafter fully described and particularly set forth in the claims.

The annexed drawing and the following description set forth in detailcertain mechanism embodying the invention, such disclosed meansconstituting, however, but one of various mechanical forms in which theprinciple of the invention may be used.

In said annexed drawing :the figure represents a central verticalcross-section of my improved water-heating device, a part of which,however, appears in side elevation. Such heater is secured upon a hollowbase A which may rest upon the floor or upon a bracket or other supportto suit the convenience of the user in view of the purpose for which hedesires to employ the device. The heating means here shown as consistingof an annular gas-burner B, are disposed within base A, the heatedproducts of combustion being conducted upwardly therefrom within thewalls of a cylindrical casing C.

The casing is surmounted by a cap C provided with an aperture 0 throughwhich connection may be had with a chimney or ventilator in order toremove the spent gases. Within the casing as above described is value,be

mounted the water-containing member D to which I more especially callattention. This member Dis essentially a hollow metal structurecomprising a central cylindrical portion d and a flange portion (1 thatwinds about such cylindrical portion. Such flange portion d, as willclearly appear from an inspection of the figure, is differently inclinedin alternate )arts certain arts as d bein sub- 6 stantially horizontalin their disposition while the intermediate parts d are inclined at agreater or less angle to the horizontal. The arrangement of thesedifferently inclined parts is such that those of successive turns of theflange that are similarly inclined are in substantially verticalalinement. Communication with the interior of structure D is had throughan inlet d that preferably opers into fian e d at its lowest oint andthrough D I i.

an outlet d at the top of the structure. A water-supply pipe (i isconnected with the former, and a water-discharge pipe (F with thelatter, of these two openings. The

structure thus described, can be very easily and cheaply cast in asingle piece, apertures (Z and d being afterward threaded for thereception of the ends of pipes (Z and (P respectively.

In order to confine the water, during its 8 5 .passage through thestructure, to flange portion d, where as is obvious it will be in moredirect contact with the heated gases arising from burner B, I providemeans for separating such flange-portion from the central 9o positionedwithin cylindrical portion (2 of 100 the structure as not to require anyother means to retain it permanently in lace. In practice I find it bestto make this p. ug in the form of a cylinder, thin sheet copper or othernon-corroding metal being the preferred material. Obviously suchcylinder need not be water tight it will satisfactorily serve itspurpose of preventing a direct upward flow of water even if it doesleak.

From the foregoing description of the con- I 10 struction of my improvedwater-heater it y will be readily seen that the water is forced Thisplug is introduced to circulate through the flat walled hollow flange dfor the entire length. of the structure D. It is accordingly thoroughlyexposed to the heated gases that ascend by way of the winding passageformed intermediately of the turns of such flange and closed laterallyby the outer casing C. The heating efl ect of these gases isconsiderably emphasized by the peculiar form given this passage throughthe disposition of the flange, alternate'parts of which, as has beenstated, are diflerently inclined. Thus the horizontal portions of suchpassage serve to retard the flow of the gases therethrough just enoughto permit the absorption by the walls of the passage of a maximum quotaof heat. And while the portions of increased inclination serve toaccelerate such flow the inclined parts of the flange-wall forming such.portlons at the same time act as baflle .lates in that they areinterposed directly in the path of the gaseous current. A similarbattle-plate effeet is, of course, afforded by the interior face of suchflange-wall in connection with the ascending current of water. A highdegree of heating efl'iciency is accordingly developed as a result ofthe double action of such inclined parts of the hollow flange.

Having thus described my invention in detail, that which I particularlypoint out and distinctly claim is 1. In a water-heating device, averticallydisposed. hollow structure comprising a central cylindricalportion and a hollow flange portion winding about the same, the turns ofsaid hollow flange portion being spaced apart and inclined upward atdifferent angles in alternate parts, and a casing fitted around theflange portion to laterally inclose the same.

2. In a water-heating device, a verticallydisposed hollow structurecomprising a central cylindrical portion and. a hollow flange portionwinding about the same, the turns oi said hollow flange portion beingspaced apart and inclined upward at diflerent angles in alternate parts,and similarly inclined parts of successive turns of said flange beingin. substantially vertical alinement, and a casing for laterallyinclosing the flange portion.

3. In a water-heating device, a vertically disposed hollow structurecomprising a central cylindrical portion and a hollow flange portionwinding about the same, the turns of said hollow flange portion beingspaced apart and disposed bothhorizontally and at an angle in alternateparts, the inclined parts being adapted to serve as balfle-plates, and.a casing fitted around the flange portion to laterally inclose the same.

4. In a water-heating device, a vertically disposed hollow structurecomprising a central cylindrical portion and a hollow flange portionwinding about the same, the turns of said hollow flange portion beingspaced apart and disposed both horizontally and at an angle in alternateparts, and similarly disposed parts of successive turns of said flangebeing in substantially vertical aliiuanent, and a casing for laterallyinclosing the hinge portion.

5. In a water-heating device, a verticallydisposed. hollow structure comprising a closed central cylindrical portion and a hollow flange portionwinding around. the same, the turns said hollow flange portion beingspared apart and difl'erently inclined in alternate parts. and a casingtitted around the flange portion to laterally inclose the same.

6. In a water-heating device, the combination with. a verticallydisposed hollow structure comprising a central cylindrical portion and ahollow flange portion winding around the same, of means in saidcylindrical portion separating it from the turns ol said nollow flangeportion, said. flange portion being spaced apart and disposed bothhorizontally and at an angle in alternate parts, and a rasing forlaterally inclosing the flange poi tion.
